“…The gluon exponent at low values of is described by the hard pomeron, as the fixed coupling LLx BFKL solution gives the value , although dependence on is expressed in the effective exponent defined in Refs. [55][56][57][58]. In the literature, fits to experimental data suggest that hard pomerons dominate the behavior of the heavy quark structure function.…”

In this article, we consider the ratio of structure functions for heavy quark pair production at low values of . The importance of this ratio for charm and beauty pair production is examined according to the Hadron Electron Ring Accelerator (HERA) data. The behavior of these ratios is considered due to the hard pomeron behavior of the gluon distribution function. The results are in good agreement with the HERA data. Expanding this data to the range of new energies underscores the importance of these measurements for heavy quarks. The ratio of charm and beauty structure functions at the proposed Large Hadron electron Collider (LHeC) is considered as a function of invariant center-of-mass energy. For top pair production this ratio is extracted with known kinematics of the LHeC and Future Circular Collider electron-hadron (FCC-eh) colliders. Comparison of the results obtained for the ratio of top structure functions in LHeC and FCC-eh are proportional to the specified inelasticity range.

We present a set of formulas to extract the ratio FL(x, Q 2 )/F2(x, Q 2 ) and R(x, Q 2 ) from the F2(x, Q 2 ) parameterization in the next-to-next-to-leading order of the perturbative theory at low x values. The behavior of these ratios studied in comparison with the fixed and effective exponents with respect to the power-law behavior of the proton structure function. The results are compared with the experimental data and the color dipole model bounds. These ratios are in good agreement with the DIS experimental data throughout the fixed value of the invariant mass. The behavior of these ratios controlled by the nonlinear corrections at low values of Q 2 . These results within the next-to-next-to-leading order approximation can be applied in the LHeC region for analyses of ultra-high energy processes in a wide range of Q 2 values.
